METHOD OF MAKING BARBED FENCING.

PEOIFIGATION forming part of Letters Patent No. 507,182, dated October24, 1893.

To all whom it may concern.-

Be it known that I, JOSEPH H. TEMPLIN, a citizen of the United States,and a resident of Reading, in the county of Berks and State ofPennsylvania, have invented certain new and useful Improvements inMethods of Making Barbed Fencing, of which the following is aspecification.

This improved method for making barbed metallic fencing consists ofproducing two barbed strips from one double blank strip by firstslitting a plain flat blank strip of metal which is equal in width totwo barbed strips to be made plus the breadth of the barbs, by two linesof parallel slits side by side and distant apart the width of the barbs,to form bars of which barbs are to be made, and to partly separate theblank; second separating said bars obliquely at the middle to completelyseparate the blank strip and point the barbs; and third bending thebarbs thus formed to project laterally from the strips as hereinafterfully described.

Figure 1 is a side elevation of the dies and face view of the upperslitting die such as may be employed and as I prefer to make them forcarrying out this improved method. Fig. 2 represents face views of someof the cutting dies and of one of each pair of the bending dies. Fig. 3is adiagram of the blank strip showing the action of the dies of Figs. 1and 2 on it. Fig. 4: represents face views of slitting dies as they maybe arranged. Fig. 5 is a diagram showing the action of the slitting diesof Fig. 4. Figs. 6, 7, 8, are side views, face view, and diagramrepresenting other different forms of slitting dies adapted foraccomplishing the same results by the same method of operations.

In the most preferable way of carrying out my said new method ofproducing two barbed strips from a double blank strip, I make twoparallel lines of straight overlapping slits 12 along the middle portionof the blank or, said lines being distant from each other the width ofthe barbs to be made, and so advanced in each line and as to therespective lines that uncut webs fg, are left between the slits of eachline opposite the middle of the slits of the other line, thus formingbars 19, for the and this completes the work. The slits b are 7preferably made simultaneously with a pair of dies j'-lc', havingsuitable cutting edges for making such interval slits without undulydistorting the metal at the ends of their slits and the diagonal slitsh, are made by cutters Z, m, of which there are two pairs, cutting eachside of the webs f and g, and they cut the lines reversely to each otherfor pointing the barbs of both strips alike relatively to them.

The benders n, are pointed suitably to punch through the cut blankbetween the slits, to bend the barbs, and benders 0, are suitablygrooved or chambered to form cavities into which the barbs may be sobent. These benders are in two pairs and cause the barbs to project inopposite directions, each pair bending one barb of each strip. They arearranged in suitable connection with the cutters for working with themand in due order of succession on the blank strip.

By another arrangement of dies that may be used, I make one long slit b,the same as b and about the length of four barbs 0. Along the striplengthwise, and parallel with it, in line with each other and similarlydistant from the said slit, I make two other slits d, 6, one of which d,is less, and the other, e, is a little more than half the length of b,said slits terminating short of each other opposite the middle of slitb, so as to leave uncut webs f, forming the connections of two barbswith one of the completed strips. The slits d, and b, terminatecoincidently at the rear ends, considering the direction in which thestrip feeds along the dies, but the slit 6, overlaps slit b, in theother direction, so as to reach the rear of the advance or precedingslit d, 5

and leave no uncut web thereat, although the blank strip feeds along thedies at each operation as much more than the length of the slit b, as isrequisite for leaving the uncut webs 9, between the slits b, for theconnec- IOO tlons of the barbs with the other of the completed strips.After making these slits I cause the bars to be cut apart and bent asabove described.

The slits b, d, e, are made simultaneously with a pair of dies j, havingcutting edges 12 d e; and 70, having edges same as k, suitably arrangedfor the purpose and also like dies j and is being of such convex form onthe faces as enables them to make interval slits without undulydistorting the metal at the ends of the slits, and the diagonal slits h,are in like manner made by cutters Z, on, of which there are two pairs,one of which cuts in this case from slit 1), to slit d, and the otherfrom said slit, 1), to slit 6, each side of the web f, and as beforethey cut the oblique lines reversely to each other for pointing thebarbs of both strips alike relatively to them.

The slits b may of course be made separately by a separate pair of diesjk, for each slit, arranged a suitable distance apart for workingindependently of and without interference with each other, asrepresented in Fig. 4, but for simpler and more compact construction itis important to contrive the dies so that they may be made in one pair.

It will be seen that although the method is very simple four barbs areproduced at each operation of the gang of dies, two on each stripproduced from the one blank.

The dies are reserved for a separate application for a patent.

What I claim, and desire to secure by Letters Patent, is-- 1. The methodof producing two barbed strips from one double blank, by making twolines of straight parallel overlapping slits along the middle of theblank, distant from each other the width of the barbs to be made, and soadvanced that uncut webs are left between the slits of each lineopposite the middle of the slits of the other line, forming bars for themaking of two barbs each, which bars are united at their ends to the twopartly separated barb strips respectively by said uncut webs, and thencutting said bars apart obliquely which completes the forming andpointing of the barbs and the separating of the barb stripssubstantially as described.

2. The method of producing two barbed strips from one double blank, bymaking two lines of straight parallel overlapping slits along the middleof the blank, distant from each other the width of the barbs to be made,and so advanced that uncut webs are left be tween the slits of each lineopposite the middle of the slits of the other line, forming bars for themaking of two barbs each, which bars are united at their ends to the twopartly separated barb strips respectively by said u ncut webs, and thencutting said bars apart obliquely which completes the forming andpointing of the barbs and the separating of the barb strips and thenbendingthe barbs laterally to the strip.
